Over the last few weeks, first some personal emails were coming with content that was line after line of letters and numbers and symbols. But could be read properly via webmail. After some Tech Help that but was OK (but font appeared different to usual) however the other emails from businesses (advertising basically) etc appeared either blank, or just not in usual 'attractive' format with pictures and text. There was minimal text interspersed with lots of info in blue starting with htpps// The same Tech Help people were unable to sort it and said to contact service provider.
